📡 The theme of b17: "In traces we find the truth"

When working with home automation protocols—and OpenWebNet in particular—official documentation and specifications can only take you so far. Between undocumented firmware nuances across gateway families (MH200N, MH201, F454, MyHomeServer1, Legrand 067292, F461), actuator configurator settings (M=0, M=1, M=4 on F411/F461), and physical motor kinetics, the only ground truth is authentic bus traces captured on live installations.

In v2.0.0b17, our community of testers and trace contributors proved this once again. By providing authentic on-wire captures from physical plants, we were able to pinpoint and eliminate elusive edge cases that could never have been deduced in theory:

1. Cover settling & limit-stop cutoff (🔬 MyHOME v2.0.0b16 Pre-Release: having a firm conversation with the firmware #770, fix(cover): settle full open/close, scope, and wall runs on travel_time + 2 s (#770) #834, fix(cover): settle a full run at the actuator's own stop up to 0.5 s before the travel time (#770 end-stop follow-up) #847): Shutters driven by F411/F461 actuators often have physical motor limits that trip fractions of a second before the programmed travel time, or run under gateways that never relay the actuator's stop status. Thanks to real hardware traces, covers now settle cleanly on travel_time + 2 s from known positions, and an actuator stop within 0.5 s before stored travel time is recognized as the true limit stop rather than freezing position at 98% or 1%.
2. BTicino 3550 99-zone Central Unit mode hydration & diagnostics (Discussion Thermoregulation with BTicino 3550 - Temperature and mode control from Home Assistant #819, test(trace): add MH200N FW 1.1.8 + 3550 central unit sweep & WHO 4 trace (#819) #845, fix(climate): hydrate BTicino 3550 (#0) diagnostic flags, repair alerts, and Dimension 12 setpoints (#819) #846): Real-plant traces unraveled the exact multi-frame initialization sweeps and active setpoints needed to fully hydrate central master units.
3. HL4684 Touchscreen FM Tuner sweeps (Discussion fix(gateway,climate): ingest H/L4684 FW 6.0.11 trace and fix H/L4684 & WHO 4 bugs (#466) #818, feat(media_player,number,button): add F500 FM tuner frequency controls, WHO 22 command/state parity & H/L4684 traces (#466) #839, fix(sound_source): cap WHO 16 station store at 1–5 & drop unreachable dim 10 branch #844): Authentic captures made it possible to implement comprehensive FM band, preset, and frequency controls.
4. Legrand 067292 gateway diagnostics (Issue [Device Request]: 067292 Gateway #832, fix(gateway): alias Legrand 067292 and 3.5" touch screen family to H4890 profile (#832) #854): Traces isolated the exact gateway identity of Legrand's DIN-rail modular gateway.
5. BTicino 3486 Central Burglar Alarm traces (test(trace): add authentic F454 FW 2.0.51 + 3486 alarm sweep & transponder trace (#466) #841, fix(alarm): advertise ARM_AWAY while refusing direct arm/disarm calls (#466) #842): Captured wire sequences allowed us to implement HomeKit arm-away mode backed by authentic replay fixtures.
6. Living Now CEN+ KW8011 wire addresses: Wire captures confirmed the addressing rules for Living Now controls and MyHomeServer1 setups.

Every single trace submitted is converted into a deterministic test fixture in CI, ensuring that no future refactor can ever break real-world installations.

🌟 What's new in v2.0.0b17

🪟 Covers (WHO 2) & Calibration

• Timed covers full run settle on travel_time + 2 s from known positions: Every full run (open_cover, close_cover, scope runs, wall-switch runs) now settles at 0% / 100% after the stored travel time plus 2 s has elapsed, even when gateways do not relay actuator stops (fix(cover): settle full open/close, scope, and wall runs on travel_time + 2 s (#770) #834).
• 0.5 s limit-stop cutoff: When the actuator stops within 0.5 s before stored travel time, it is recognized as a full limit stop, eliminating 1% / 98% frozen positions (fix(cover): settle a full run at the actuator's own stop up to 0.5 s before the travel time (#770 end-stop follow-up) #847).
• Configurable min_position_delta (1–5%, default 2%): Allows fine-grained 1% adjustments for tall blinds and precise slat tilts (feat(cover): per-cover min_position_delta for advanced covers #778).
• Translated stop frames (*2*1000#0*WHERE##) halt timed runs: Gateways that relay scenario or keypad stops as translated frames now properly stop timed runs (fix(cover): settle full open/close, scope, and wall runs on travel_time + 2 s (#770) #834).
• Calibration limit guards: myhome.calibrate_cover refuses runs ending near whole-minute configurator cutoffs (59–65 s, 119–130 s on F411 at M=1, up to 10 min) ([Bug]: calibrate_cover stores the F411 120 s cutoff (M=1) as a travel time #837, fix(cover): refuse every configurator run-time limit in calibrate_cover, not only 60 s (#837) #843).

🌡️ Climate & Thermoregulation (WHO 4)

• BTicino 3550 99-zone Central Unit hydration: Mode hydration, active setpoint management, and diagnostic flags for master control panels (Discussion Thermoregulation with BTicino 3550 - Temperature and mode control from Home Assistant #819, PR test(trace): add MH200N FW 1.1.8 + 3550 central unit sweep & WHO 4 trace (#819) #845, fix(climate): hydrate BTicino 3550 (#0) diagnostic flags, repair alerts, and Dimension 12 setpoints (#819) #846).
• Thermo Actuator Switch Platform: New switch entities to manually actuate heating solenoids on demand (Issue climate zone ON/OFF #785, PR feat(switch,climate): support WHO=4 probe-less thermo actuator switches (#785) #817).
• Interface routing, actuator guards, humidity poll gates, and pump ghost filtering (fix(climate): show the setpoint in force (dimension 12), keep dimension 14 as the commanded value #791, feat(climate): request actuator status (dimension 20) on add and after reconnect, expose actuators, derive hvac_action #792, fix(climate): do not poll humidity (dimension 60) where the emulated firmware did not forward it #793, fix(climate): gate unrouted WHO 4 #4#II and actuator status polls #816, fix(climate,i18n): prevent WHAT 4001/4002 ghost re-spawn on Z#N thermo switches and localize subentries (#785) #825).

💡 Lighting & Dimmers (WHO 1)

• Fine dimmer preset echo & coarse curve alignment: Fixed preset echo synchronization on fine dimmers (WHAT 101–199) and autodiscovered dimmers ([Bug]: a coarse WHAT 2..10 status reply overwrites the exact DIMENSION 1 level of a fine dimmer (F418 on F461) #851, fix(light): ask Dimension 1 after a coarse preset echo on a fine dimmer (#851) #852), and aligned coarse preset curve values with hardware dimming levels (fix(light,expose): map coarse WHAT 2..10 presets via BTicino dimmerLevelTo100 curve (#466) #828).
• Actuator & detector coexistence: Clean coexistence when a lighting actuator and motion detector share the same SCS address WHERE ([2.0.0b16] Configured light removed on reload after motion sensor discovery at the same WHO 1 address (F454 / Legrand 067226) #777, fix(light): keep a configured light when a WHO 1 motion sensor shares its address (#777) #781).
• Dimension 22 guard form crash fix (fix(thermo): follow OWNd's dimension 22 crash-form detector instead of blocking every split-control frame #849).

🔊 Sound System & Burglar Alarm

• F500 FM Tuner platform controls: FM tuner entities now support band, preset, and frequency controls with live HL4684 trace replay (feat(media_player,number,button): add F500 FM tuner frequency controls, WHO 22 command/state parity & H/L4684 traces (#466) #839, fix(sound_source): cap WHO 16 station store at 1–5 & drop unreachable dim 10 branch #844).
• Burglar Alarm HomeKit arm-away mode: Added read-only HomeKit arm-away mode backed by live BTicino 3486 central unit alarm trace replay (test(trace): add authentic F454 FW 2.0.51 + 3486 alarm sweep & transponder trace (#466) #841, fix(alarm): advertise ARM_AWAY while refusing direct arm/disarm calls (#466) #842).

🔌 Gateways, Engine & Protocol

• Upstream OWNd 2.0.0b13 integration (chore(deps): pin OWNd==2.0.0b13 and close the OWNd#139 / #142 / #147 transition windows #848).
• Profile alias for Legrand 067292 gateway (Issue [Device Request]: 067292 Gateway #832, PR fix(gateway): alias Legrand 067292 and 3.5" touch screen family to H4890 profile (#832) #854).
• Per-firmware startup requests (fix(gateway): skip the startup requests the firmware refuses, poll each zone's temperature on SCS-only gateways #794) and manual gateway model identification (feat(config_flow): identify a manually added gateway after authentication #804).
• Door-entry WHO 6 gateway boundary enforcement (fix(lock,topology): surface WHO 6 gateway NACKs, support WHO 6/8 delegation & document MH/AV bus boundaries #835).
• Resolved flaky multi-gateway dispatcher callbacks (fix(test): wrap test dispatcher callbacks with callback() to eliminate executor thread race #850).

🛡️ Quality & Test Engine

• Over 5,300 automated tests passing with 100% statement coverage (5,324 tests) (+931 tests since b16).
• Strict Home Assistant architectural standards (Platinum 54/54 rules satisfied, PARALLEL_UPDATES = 0 across all 11 platforms).
• Full compatibility with Home Assistant 2026.11 / 2026.12 (compat_name, logger compat, deprecation guards).

⚠️ Behaviour changes to check after updating

1. Cover Full Runs & Timing: Verify that timed shutters driven to full open or full close report 100% / 0% cleanly, and that stops near the end settle smoothly.
2. Central Heating Units: Users with BTicino 3550 central units should check that diagnostic flags and modes reflect the master panel state.
3. Fine Dimmers: Dimmer presets and sliders should follow the hardware smoothly without jumping back.

[gdluck]

First of all, thank you for all the work on MyHOME, and congratulations on the v2.0.0b17 pre-release.

A status note from the OWNd / MyHOME audit side, for the record here. The fixes now in flight are the last protocol-level findings. The file-by-file audit of OWNd and MyHOME was cross-checked three ways, DeepSeek, Kimi and Claude, against the official WHO documents and the firmware oracle, and the few points where the reviewers disagreed were settled on the F461 test plant rather than argued. What survived that check is being fixed in the open PRs: a WHO 7 camera WHERE zero-pad, a send-layer guard for the WHO 18 dimension 52 four-digit-year frame that crashes F460/F461, WHO 14 General and Area addressing per the WHO 1 PDF table, a WHO 13 note on the dimensions 10/11/12 that crash H4684/MH200, and the bare WHO 22 power frame that crashes the sound daemon on F461/F454 (the with-source form goes out clean).

After this round we do not expect further findings that come from misreading OpenWebNet. Whatever is left is integration logic, cover calibration being the obvious example, not a misinterpretation of the protocol. Thanks again for making this a repository where the traces decide.
